为了验证47%春雷·王铜(加瑞农)可湿性粉剂对稻曲病防治效果,评价其对水稻生长发育的安全性。2010年9～10月,我们在晚稻上进行了47%春雷·王铜(加瑞农)防治稻曲病试验。1材料与方法1.1试验条件试验在蔡甸区张湾街辛集村肖永喜晚稻田进行。试验田土壤类型为潮土,PH 6.5,有机质含量25g/kg,土壤肥力中等。试验田地势平坦,排灌方便,肥力水平等均匀一致,稻曲病常年发生较重。栽培品种为嘉优2号,较感稻曲病,2010
In order to verify the control effect of 47% Chunleiwanglu (Garrengine) WP on rice false smut and evaluate its safety on the growth and development of rice. From September to October 2010, we conducted 47% spring rice trial on rice false smut in Spring Rice. 1 Materials and methods 1.1 Test conditions Test in Caidian District Zhang Wan Street Xinji Village Xiao Yongxi late rice fields. The soil type in the experimental field was alluvial soil, pH 6.5, organic matter content 25 g / kg and medium soil fertility. Flat field test, irrigation and drainage convenience, fertility level uniform, False false smut is more serious. Cultivar varieties Jiayou 2, more susceptible to smut, 2010
